Safe and Smooth Traffic Control

Road Traffic Signal Controllers provide safe and smooth road traffic by conducting road traffic control in accordance with the time of day and the road traffic conditions, and also perform advanced road traffic control to eliminate road traffic congestion. Suitable also for crosswalks with multi-information displays, they are replete with many additional functions.
The benefits of ARTEMIS, an autonomous distributed signal controller developed by the Company, have also been recognized in various overseas countries that have adopted it.

Autonomous Distributed Signal Control (ARTEMIS) Functions

ARTEMIS is an environmentally-friendly road traffic signal controller that relieves road traffic congestion and contributes to the reduction of CO2 and nitrogen oxide emissions.
With a typical road traffic signal controller, the length of time that the traffic light is green is determined at the traffic control center based on past road traffic data measured by vehicle sensors. With ARTEMIS, however, the road traffic signal controller itself determines the optimum period of time for the light to remain green in real time by means of road traffic signal controllers positioned at intersections exchanging information among themselves.

Disaster Prevention-type Road Traffic Signal Controllers

These are traffic signals equipped with a special function that display a red light to prevent cars heading for the city center from approaching it in the event of a major earthquake.

Level Crossing Interlocking Road Traffic Signal Controllers

These controllers eliminate the need for a temporary stop at the level crossing and ensure the smooth flow of road traffic. Information obtained from adjacent intersections and railway facilities can alleviate road traffic congestion and increase safety at level crossings.
